Description
Technical field
The utility model belongs to the biomass gasification technology field, particularly a kind of gasifying biomass generating unit.
Background technology
China's straw amount of biomass is big, kind is many, distribution is wide, if can obtain abundant rational and efficient use, both can increase farmers' income, and saves and substitutes resources such as a large amount of timber and coal, can also reduce the discharging of a large amount of greenhouse gases.About Biomass Energy Utilization, more feasible at present way is with biomass solid and gasification, aspect gasification, because biomass contain a large amount of volatile matters, use present biomass gasification device,, largely restricted the development and the popularization of gasifying biomass owing to produce a large amount of tar problems.
Summary of the invention
The purpose of this utility model is to make the composition that contains dust in the gas of production few, the biomass gasification device that tar content is low.
The purpose of this utility model can realize by following technical measures:
This gasification installation connects furnace body support at the last vapourizing furnace body of heater that is connected with loam cake, the body of heater that is positioned at the fire grate top is provided with biomass feed inlet, on the gasification furnace chamber of fire grate top last furnace chamber is arranged, the upper and lower part is provided with gas extractor and heat-exchanger rig respectively in the gasification furnace chamber, is arranged in the water tank with strainer that is connected in the body of heater outside under the gas transmission main in heat-exchanger rig and the gas extractor outside.
The purpose of this utility model also can realize by following technical measures:
Heat-exchanger rig is double-deck be interconnected and tubulation; Gas extractor comprises the also tubulation that porous is interconnected and is positioned at the also anti-stream plate on tubulation top; The gas transmission main in the body of heater outside is connected with air pump; Under the fire grate dust collecting box is arranged.
Incineration grate of the present utility model is positioned at lower part of body of heater, be provided with double-deck heat-exchanger rig on the top of incineration grate, biomass fuel burns at the incineration grate place, produced more volatile component, these volatile components enter the gasification furnace chamber that is positioned at the body of heater middle part from burning chamber, be collected at the anti-stream plate at gas extractor place and the collection place of being in charge of and enter the gas delivery house steward, process heat-exchanger rig and corresponding conveying, refining plant finally produce comparatively purified biological fuel gas in the water tank exit then.
The utility model utilizes in the combustion gas that heat-exchanger rig and refining plant produce dust and tar ingredients less, thereby makes the burning of biological fuel gas become clean more, fully.
The gas extractor of upper of furnace body comprises that the formation air-flow instead be in charge of and the delivery manifold by the anti-stream plate and the porous collection of stream, it between collection and confinement of gases zone and combustion zone a gasification furnace chamber, the dust that burning produces comes off in the gasification furnace chamber mostly, makes that ash content is less in the gas that upper of furnace body is collected.Anti-stream plate is positioned at the top of porous collection tube, the top of anti-stream plate is the last furnace chamber of body of heater, because the effect of anti-stream plate, air-flow forms anti-stream, because shrinkage makes a part of gas become drop, and accumulate in anti-stream Board position, the porous that is positioned at anti-stream plate below is collected the drop of being in charge of collection formation, and these liquid components are biomass mostly, after drop enters and is in charge of, import transfer lime and enter heat-exchanger rig, be heated and be converted to gas.
Transport house steward the drop collected etc. is delivered to heat-exchanger rig downwards, heat-exchanger rig is positioned at the top of combustion zone, has higher temperature herein, and the mixture of gas and drop is heated at this and promotes to change into gas.Interchanger is a bilayer structure, purpose is that heat exchange can be compared fully, profile is rounded, utilize the piped heat exchange mechanisms to increase heat interchanging area, UNICOM between each pipe, heat exchange takes place through each Guan Shiyu outside in gas stream, the heat-exchanger rig on the upper strata of at first flowing through, and the heat-exchanger rig from lower floor flows out then.At the heat-exchanger rig place, made full use of the gas of the heat heating collection of burning generation.
Because whole pipeline is longer, so will keep mobilely, the place installs off-gas pump additional at export pipeline, is positioned at the downstream pipeline with air pump, utilizes electric motor driving, when off-gas pump work, makes to produce pressure reduction before and after the off-gas pump, has kept the mobile of air-flow.As cleaned water tank, cleaned water tank is positioned at the end of pipeline to air-flow with laggard, and tar ingredients is removed at cleaned water tank, and the outlet of gas is arranged in the other end of water tank, obtains purified biological fuel gas at this.
The existing biomass gasification device that uses in use produces a large amount of tar.At this situation, the present invention utilizes the high calorie that produces in the gasification, and most of tar further is decomposed into the small molecules inflammable gas, through water elution tar, obtains more purified combustible gas.
The utility model utilizes the more characteristics of biomass volatile matter, utilizes gas extractor and heat-exchanger rig and refining plant to obtain purified biological fuel gas.Its characteristics that are different from other gasification installations are, because gas extractor separates with the combustion zone, it is less to collect the gas dust, but contain tar ingredients, utilize the heat effect of heat-exchanger rig, impel a part of tar to change gaseous state into, simultaneously, adopt water tank and off-gas pump, the tar that is mingled with in the gas of collecting is removed.
